TB62208FG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB62208FG BiCD Constant-Current Two-Phase Bipolar Stepping Motor Driver IC The TB62208FG is a two-phase bipolar stepping motor driver using a PWM chopper. Fabricated with the BiCD process, the TB62208FG is rated at 40 V/1.8 A. The on-chip voltage regulator allows control of a stepping motor with a single VM power supply. HSOP28-P-0450-0.80 Features Bipolar stepping motor driver Weight: 0.79 g (typ.) PWM constant-current drive Provides phase-A and phase-B enable inputs to allow 2-phase and 1-2-phase excitation. BiCD process: Uses DMOS FETs as output power transistors. High voltage and current: 40 V/1.8 A Thermal shutdown (TSD), over-current shutdown (ISD), and power-on-resets (PORs) for VMR and VCCR Package: Heat-sink Small Outline Package (HSOP28-P-0450-0.80) 2014 TOSHIBA Corporation 1 2014-10-01 TB62208FG Block Diagram FIN&LOGIC GND 28 27 26 25 24 23 22 21 20 19 18 17 16 15 Reg Pre-driver ISD Comparator TSD Comparator ISD Control Pre-driver 10 1 2 3 4 5 6 7 8 9 11 12 13 14 FIN&LOGIC GND In the block diagram, part of the functional blocks or constants may be omitted or simplified for explanatory purposes. 2 2014-10-01 NC OSCM NC Vref A PHASE A Vref B PHASE B NC ENABLE A NC ENABLE B VCC STANDBY VM RS A RS B NC NC OUT A OUT B NC NC PGND PGND OUT A OUT B PGND PGND
